Once you catch on the setting 30-30 shoulder back just right to make 30 Herrett cases (it's tricky, and I can elaborate if anyone wants to discuss it) then comes the issue of accurate loads. There just isn't much data available.

It seemed to me 30 Herrett isn't too far from what could be called 7.62x39R. AA 1680 was supposedly developed for that cartridge so I gave it a try, reducing starting loads for 130 grain bullets.

Hornady shows WW296 with magnum primers for that weight bullet so I shot a group that didn't turn out too bad.

Tried AA 1680 as shown which shot 2 groups seen here. I'm sticking with that powder. No velocity since my chronograph was on the fritz. SW

Time to clear up the confusion... Here's my Contender with 14" 30 Herrett barrel. Also shown in my 10" 41 Mag barrel.

Then there's the steps in making 30H cases. Left to right...

Once fired 30-30 caseSame run through the FL die to set the shoulder backThen trimmed to 1.6"Fire formed to blow the shoulder out to 30 degrees.(No need to square the cases up - the lens distorted the image because I took the pic way close)

The case trimmer is hand crank, but I cheat & use a drill adapter = mucho faster.

And a full box ready for the range. 130 grain boolet.

So why go to all the bother? 30 Herrett was developed for metallic silhouette matches. I won a trophy or three with mine. 30H is also more efficient. 30-30 will give you a big fireball which isn't what you want. Powder burning outside the barrel isn't doing you much good. Like mastodon whacker loads in a 2.5" 357.

Plus it's fun to work up accurate loads where none can be found! SW
